Analysis of Frequency Selective Surfaces for Radar Absorbing Materials

Nowadays, applications of Frequency Selective Surfaces (FSS) for radar absorbing materials (RAM) are increasing, but it is still a challenge to select a proper FSS for a particular material as well as the dimensions of FSS for optimized absorption. Therefore, in this paper an attempt has been made to optimize the dimensions of FSS for microwave absorbing application using Genetic Algorithm (GA)...

Absorbing boundary conditions for electromagnetic wave propagation

In this paper, the theoretical perfectly absorbing boundary condition on the boundary of a half{space domain is developed for the Maxwell system by considering the system in whole instead of considering each component of the electromagnetic elds individually. This boundary condition allows any wave motion generated within the domain to pass through the boundary of the domain without generating ...

Design of Broadband Radar Absorbing Materials Using Particle Swarm Optimization

The design of planar multi-layer coatings with high absorption for a desired frequency and angle range is presented. The design technique is based on Particle swarm optimization (PSO). PSO is an evolutionary optimization algorithm based on the bird fly. Several design cases are presented. Numerical results that are compared with the existing in the literature show the advantages of this approac...

Electromagnetic Wave Absorbing Properties of Amorphous Carbon Nanotubes

Amorphous carbon nanotubes (ACNTs) with diameters in the range of 7-50 nm were used as absorber materials for electromagnetic waves. The electromagnetic wave absorbing composite films were prepared by a dip-coating method using a uniform mixture of rare earth lanthanum nitrate doped ACNTs and polyvinyl chloride (PVC). The microstructures of ACNTs and ACNT/PVC composites were characterized using...
